Hi,

running 0.12.5 with a Ubuntu LTS 10.04.1 64-bit kernel I see the following error after a few days with severe load (constant 100-200mbps input).

# uname -a
Linux ubuntu-newsfeed 2.6.32-24-server #43-Ubuntu SMP Thu Sep 16 16:05:42 UTC 2010 x86_64 GNU/Linux

Linux newsfeed-spool 2.6.27.48-0.2-default seems not affected. I have a machine with even higher load (about 300-400mbits constant
network load) up for 4 months without a crash.

Is this anything known?

After this error, the network device hangs. However, it can be recovered by setting ip link down and up again.
